Carnivore Diet: Is It Good For You? A Heart Doctor Explains

Win the battle, lose the war? The Carnivore Diet, as explained by a preventive cardiologist. Background: The carnivore diet has surged in popularity on social media, promising rapid weight loss and relief from chronic symptoms for a variety of diseases. But from a preventive cardiology standpoint, it represents an extreme and potentially harmful departure from healthy nutrition. Decades of data... from the Framingham and INTERHEART studies to modern genetic analyses like Ference's in JAMA Cardiology confirm that elevated LDL cholesterol directly causes atherosclerosis. Diets high in saturated fat and devoid of fiber predictably raise LDL, reduce gut microbiome diversity and may accelerate the very diseases they claim to prevent. While eliminating processed foods and refined carbohydrates is beneficial, cutting out all plant foods is not. Evidence from landmark trials such as PREDIMED and DASH demonstrates that Mediterranean-style, whole-food, plant-forward eating patterns - with lean proteins, healthy fats, and yes, fiber - reduce cardiovascular events and improve longevity. The carnivore diet may provide short-term benefits through caloric restriction, but its long-term risks are well-documented. Sustainable heart health doesn't come from extreme fringe diets, but from effective, balanced, evidence-based nutrition. Studies mentioned in this video: The Framingham Heart Study (Dawber et al., 1951, Am J Public Health) first established the concept of cardiovascular risk factors, linking high LDL cholesterol, smoking, and blood pressure to heart disease. The INTERHEART study (Yusuf et al., 2004, Lancet), conducted in 52 countries, confirmed that nine modifiable risk factors, including cholesterol, explain the majority of heart attack risk worldwide. The Cholesterol Treatment Trialists’ Collaboration (CTT Collaborators, 2005, Lancet; 2010, Lancet) showed in meta-analyses of randomized trials that lowering LDL cholesterol reduces cardiovascular events in a dose-dependent way. A 2022 analysis by Ference and colleagues (JAMA Cardiology) confirmed genetically that LDL cholesterol is causally related to atherosclerosis, demonstrating that lower LDL levels throughout life mean lower cardiovascular risk. Keys’ Seven Countries Study (Keys, 1970, Circulation) connected saturated fat intake with cholesterol and heart disease but led to the over-simplified low-fat craze, which drove food companies to replace fat with added sugar. Later metabolic ward studies, such as Hall et al. (2015, Cell Metabolism), showed that calorie balance matters most, while Ebbeling et al. (2018, BMJ) found that lower-carb diets may slightly increase energy expenditure during weight maintenance. The DIETFITS trial by Gardner et al. (2018, JAMA) demonstrated that diet quality is more important than whether a diet is low-carb or low-fat. The PREDIMED trial (Estruch et al., 2013, NEJM) provided strong evidence that a Mediterranean diet rich in olive oil, nuts, legumes, and fish reduces cardiovascular events, while the DASH diet (Appel et al., 1997, NEJM) proved effective for lowering blood pressure and improving lipids. More recently, O’Hearn et al. (2021, Current Developments in Nutrition) published a survey of carnivore diet adherents showing common reports of hypercholesterolemia and nutrient deficiencies, raising concern about long-term cardiovascular safety. Finally, research by Zmora et al. (2019, Cell) showed that diets lacking fiber impair the gut microbiome’s production of protective short-chain fatty acids, underscoring the importance of plant foods for long-term health.
